Crystal Growing

Mould fun plaster shapes, including stars, lightning bolts, dolphins, and pyramids, and grow layers of crystals on them. Use dyes to form coloured crystals, and mix the dyes to grow a rainbow of custom coloured crystals.

Display your crystal creations in a clear treasure chest with a locking lid. Mould your own geode — a hollow rock with crystals growing inside — and create a beautiful crystal cavern inside. Experiment with growing crystals rapidly and slowly, and observe how that affects the crystal structures. See if you can grow one giant crystal, and many small crystals on the surface of a rock.
